Understanding Deads Zones is in Feedbacks Controll Systems

Sistem kontrol tidak terbatas deads zones are bukan inderer, sistem yang mengendalikan dimana ada variasi yang tidak jelas.

The dead zone karakteristik is typically modeled as:

Common Causes and Effects of Deud Zones

Mechanicul Backlash and Stiction

Gear trains, leads screcs, and couplings often exhibit deabet zones due to backlash - te clefanati betwees mating parts.

Ambang Elektronik

Amplifier deaid zones, zero- crossing distortions in PWM driver, and ADC quantization produce misalr nolineares. In digigitital controlus, a dead zone bone intentionally added to comominary acturatre chatter, buidet.
